The function uart_irq_rx_ready() should return true if there is data in
the receive buffer, regardless of whether the irq is enabled. Fix the
mcux and rv32m1 shim drivers to implement this behavior correctly.
Prior to this change:
- irq_rx_full() checks if RX data is available
- irq_rx_ready() checks if RX data is available and interrupts are
enabled
After this change:
- irq_rx_full() checks if RX data is available
- irq_rx_ready() renamed to irq_rx_pending() to avoid confusion with the
API ready() function
- API ready() implementation switched to use irq_rx_full()

socket_can_generic.h makes some assumptions that are not always valid
for various drivers with regards to numbering. To clean this up we
add defines for SOCKET_CAN_NAME_0 and SOCKET_CAN_NAME_2 in addition to
SOCKET_CAN_NAME_1.
We also move struct socket_can_context into the drivers themselves
since they know best how many CAN interfaces are getting supported and
what naming/number convention they'd have.
Additionally, this also exposes a few other build issues with the
can_mcux_flexcan driver that get fixed.
Finally, we remove the platform_allow from samples/net/sockets/can
since it is no longer needed.

Force sx12xx modems into sleep mode on boot. This is the default state
of the modem when not being used due to the TX/RX complete callbacks.
This reduces current consumption by 600uA before the modems are used
for the first time.
As sleep is the normal state after TX/RX when using the LoRa API, it is
garaunteed that this will not change the behaviour of application code.
LoRaWAN starts by calling Radio.Init(), which resets the modem, so any
sleep configuration we do here is discarded.

There was a regression when implementing automatic AT+CWMODE{,_CUR}
handling based on driver needs. ESP AT 1.7 firmware does not support
AT+CWMODE_CUR=0, which means that radio needs to be either in STA, AP or

Change type of esp_socket->flags from uint8_t to atomic_t, so that read
and write access to those flags is done in atomic (thread-safe) manner.
Introduce esp_socket_ref() and esp_socket_unref() functions, which
operate on atomic refcount variable. esp_socket_ref() role is to
increase refcount if it was already non-zero. If it was zero then NULL
is returned, which means that socket is not used by net_context at the
moment.
Role of refcount:
* socket instance is assured to be between net_offload->get() and
net_offload->put() when refcount > 0,
* makes sure that socket instance can be used (its members can be
dereferenced) when refcount > 0,
* 'context' member is always valid and its members can be dereferenced
when refcount > 0.
esp_socket_get() gets unused socket, as previously. Additionally it sets
refcount to 1 at the end of call, which basically means that from that
point such socket can be referenced by other parts of the driver. Each
esp_socket_get() call should be followed by esp_socket_unref() and
esp_socket_put() to properly invalidate socket and prevent other parts
of driver from using it.
Add ESP_SOCK_WORKQ_STOPPED flag, which is now used to prevent scheduling
more work into driver workqueue. This flag is set in net_offload->put()
callback, so that no more socket work (such as processing RX/TX packets
or closing socket because of errors) is submitted after that.
Introduce mutex lock, which has following role:
* protects dst, connect_cb + conn_user_data, recv_cb + recv_user_data,
* assures that checking ESP_SOCK_WORKQ_STOPPED flag and actually
submitting (or not if net_offload->put was already called) new socket
work to workqueue is done in atomic way.
As there is a mechanism to prevent submitting new work items to
workqueue when net_offload->put() has been executed, then there is no
need to explicitly call esp_socket_ref() in esp_workq thread. This is
because one reference is being held by net_context (after calling
net_context->get()). This is why all the esp_socket_in_use() were simply
dropped. Code running from esp_rx thread on the other hand always uses
esp_socket_ref_from_link_id() helper function (which is backed by
esp_socket_ref()), so that it replaces previous esp_socket_in_use()
calls and additionally makes sure that socket stays valid ("in use")
until esp_socket_unref() is called.

Currently, if no net_pkt's are available, the radio driver RX thread
drops the 802.15.4 frame silently. This causes undesired behaviour,
where we can drop the packet which has already been acknowledged at
the 802.15.4 level.
Fix this, by blocking the RX thread if no net_pkt is avaliable. The
packets received while the RX thread is blocked will be accumulated in
the underlying nRF 802.15.4 driver, and eventually when it runs out of
internal buffers before the thread is unblocked, it'll stop
acknowledging the incoming frames.

Introduces a new flash driver for the FlexSPI peripheral on i.MX RT
SoCs. The hardware provides a flexible sequence engine (LUT) that
supports various types of external devices, including serial NOR flash,
serial NAND flash, HyperBus (HyperFlash/HyperRAM), and FPGAs. It
supports up to four connected devices in single/dual/quad/octal modes
and provides memory-mapped read/write access to these devices through
the AHB bus.
The driver implementation consists of a shared controller for each
FlexSPI peripheral instance, and protocol-specific device drivers for
each external device. The controller provides a private interface for
multiple devices to access the FlexSPI peripheral registers. FlexSPI
devices provide the public flash driver interface to applications or
subsystems like storage or flash file systems; they also provide
protocol-specific LUT sequences to the controller.
Currently the only device type supported is QSPI NOR flash, but other
types like HyperFlash will be added later.
XIP is not yet supported, as this requires additional work to relocate
code to RAM and managing interrupts.

So far a dedicated FIFO was used for all RX packets, which was consumed
in single submitted work. This work was also responsible for closing
socket and notifying uppper network layers if some errors occurred
previously or socket was simply closed by peer. There is however a
potential race condition in scenario described below:
esp_rx thread | esp_workq thread
--------------------------|-----------------------------
| ---- esp_recv_work ----
| handle RX packets from FIFO
|
---- on_cmd_ipd ---- |
put new RX packet to FIFO |
---- on_cmd_ipd ---- |
|
---- on_cmd_closed ---- |
mark socket as closed |
---- on_cmd_closed ---- |
|
| handle close
| ---- esp_recv_work ----
In this case we assume that esp_workq was preempted just after
processing all RX packets from FIFO and before checking if socket was
closed. In such scenario RX packet put to FIFO just before doing close
is going to be unhandled, so application layer will miss part of the
data.
Change the way RX packets are scheduled to workqueue, by using the
already available net_pkt->work objects (used for example in native TCP
stack). Create a separate work for closing connection. As a result all
RX packets and close handlers are on the same queue and there is no risk
of handling close events before handling all previously received data.

Currently there are two code paths when sending packets:
asynchronous (using workqueue) when zero timeout was specified and
synchronous in other cases. This doesn't seem to be justified, so
convert code to always schedule packet sending using workqueue.
Each net_pkt has an embedded work item, so use it instead of esp socket
specific work that was shared across all sent packets. This gives a
possibility to schedule multiple packets for sending.
